Platinum, Palladium or Rhodium-
plated objects
The measurement result of the CaratScreenPen is influenced not only by the gold content but
also by other metals, especially silver and palladium. Thus, a high content of silver or palladium
leads to a sometimes significantly higher result (output in the adjacent transition range or in
the range of the next higher carat number) than the hallmarking of the object would suggest.
This is because 14 K or 585 simply mean that the object has a gold content of 585 ‰. However,
the composition of the other 415 ‰ depends on numerous factors. The desired color plays an
important role: e.g. yellow gold, red gold, or white gold. The more reddish a piece of jewellery
(rosé gold or red gold), the more copper is in the alloy. In white gold, on the other hand, the
proportion of silver, nickel, palladium or zinc is significantly increased.
Beware of the following hallmarks "plated" /
"double" / "americaner" / "alpaca/alpaca": These
are only galvanically applied gold layers on non-
precious materials or so-called nickel silver.
Beware of so-called "Autobahngold": These are
low-value jewellery objects made of brass or
stainless steel with or without thin gold plating,
which are mainly offered at rest stops and gas
stations. E.g. jewellery with hallmarks in the format
"18K-0.750", whereas the real hallmark is in the
format "18K-750".
Please inform yourself about country-specific
hallmarks, seals of quality and minting on the
Internet.
If the cursor flashes in the right, blue range, it is an
object made of platinum or platinum or a rhodium-
plated piece of jewellery. Please not the important
information in the previous chapter. Caution: In
some cases, V2A stainless steel is also in this range.
Please note that this value range applies to the
respective pure forms and high-alloyed jewellery
alloys. For instance, the frequently used palladium
500 lies in the range of 12-14 carat gold.
